' c aims; (Cristist) i This invention relates to circular window constructions, and has for its general object a circular window construction, which is extremely simple and economical'in manufacture, highly efficient and durable in use; andwhich may be sold at such a low price that it is practical for use in such vehicles, as trailers, and in other situations, where a low priced, high class win dowis'imperativeu, l

- Itfurther has for its object a; circular window construction including a circularwindow frame and a circular discoidalsash rotatably mounted inthe' window framean'd composed of two semi circular or semi-discoidal;sections of different character, as one with a glass pane and the other withv ascreen, with theglass section nor mally exposed in a-semiI-circular window open ing in the body of the vehicle, the. other section located in well "in-fthe vehicle body, with-the sash rotatable in the window frame to shift the entire sash carry, one. section wholly or partly intofthe well and the other section wholly or partly into the semi-circular window penjng It further has for its object circular window frame -for such a sash in which one half of the frame extends into, a well -having a semi-"annularflange and a diametrically extendingflangeforming a facing 3 for the semi-annular margin of the wall around the window open "ingand a sill piece extending along the base of the semi-circle of said opening. y

The invention consists in the novel features and in the combinations and: constructions hereinafter setforth' and claimed.

In describing this invention, reference had to the accompanying drawingsin which like characters designate corresponding parts in all the views. I Y

The body is also formed with a frame members ex- Figure 7 is a sectional viewon' line l'-l' Fig-- tending along the loase of the semi-circular;

opening. The semi-circular opening is usually arranged with its base line extending horizontally and with the well below the window openl designates the circular window frame which includes a bodytfl fitting in the semi-circular wall of the window opening t and extending into the well 5; The body 8 isformedwith"a'sash guide,v here illustrated as an inwardly extending annular rib 9. The body is also formed with a semi annular flange it arranged at a right angle to the body 8 and forming a facing for the semi-annular margin of the wall E-around the window opening 4, and also with a diametrh cally extending horizontal sill facing flange at.

H. The flange iii also extends inwardly at l2 parallel to the rib 9. The half of the window frame which extends into the well 5 is unpro-' vided with a facing flange it. The frame I is secured in the window opening by. fastening the flange being here shown as having a glass pane or panel I and the other'a screenv panel. The circular sash frame i3 has a diametrically extending rail or bar l6 which separates the glass section from the screen section. Thesection it and the bar-HS is formedwith a r'e-entrant groove H for re.- ceiving the margin of the, glass pane, a suitable glazing strip It being located in the groove. .The lower section 55 of the frame of the sash l3 and also the bar It is formed with a recess it, angu lar in, cross section, for receiving themargin of the screening, the margin being clamped in the: recess 18 in any suitable manner, as by glazing strips, 2|. The sash is formed with a peripheral groove for receiving the guide rib 9, a suitable non-metal U-shaped weather and wear strip 20 being located in the groove.

One side of the re-entrant groove I! and the side of the angular recess I8 is here shown as removable, this removable side being preferably a flat annular ring 22 having a diametrically extending rib 23. The ring 22 and rib 23 are secured respectively, to the circular portion of the sash frame and to the bar It, as by screws 24. This is primarily for the purpose of facilitating the mounting of the sash in the window frame with the rib 9 in the peripheral groove .28 i

of the sash frame. It'also serves to facilitate re-glazing and for renewing the screen. Preferably, a weather strip is carried by the transverse sill facing flange I! of the window frame,

this coacting with the diametrically extending bar IE or the removable side 23 thereof, particularly whenthe sash is in normal position or when the glass section entirely closes the window open"- 7 ing.

A suitable handle or handles may be provided for turning the window sash in the window opening, these being located preferably near the peripheral edge of the sash, and as here shown,

.thewindow frame is provided with webs 26 in the corners formedby the transverse member or bar l6, where it meets or joins the circular sash frame,

screen side of the sash will then be in position to again rotate the circular frame, so that the sash may be rotated to again bring the glass into position to fully close the window opening and locate the screen entirely below the well.

In assembling the window frame in the body of the vehicle, with or without the sash in the 1 window frame, the window frame is lifted and tilted out of the vertical slightly, so that the lower screen section thereof can be inserted in the well, and then the upper end of the screen swung inwardly into the window opening and secured thereto.

In Figure 7, 3| designates the framing of the body of the vehicle, and 32, 33 the inner and outer walls or facings of the body which are secured to the framing 3|. The body isformed'with a semi-circular window opening, as in Figure 1, and with a well at one side of the opening. The body is also formed with a transverse frame member 36 extending along the base of the semi-circular opening. The semi-circular opening is usually arranged with its base line extending horizontally and with the Well below the opening.

31 designates the circular window frame, which includes .a body fitting into the semi-circular window opening and also extending into the well below the opening, the body having the facing flanges, corresponding to the flanges H3, l2 (Fig- Iures 1, 2 and 3).

The window frame (Figure 6) is for the most part of the same construction as that shown in Figures 1 and 2, with the exception that the circular window frame is a split ring out transversely at S and capable of being expanded slightly, and with the further exception that the diametrically 5 extending horizontal sill facing flange 4|, corre- 2,197,074 J of the window frame Itisf'here shown, as se I cured at its ends to the window frame'byscrews framing thereon-as by screws-.43. jThe screws and into the window frame and the screws 43 pass through the flange 4| intof'the frame in the Wall structure of the vehicle around, the win?- dow opening. The sill facing 4| is provided with an angular flange 44 which overhangs the; sill 42 and also secured to the vehicle body orthe h k.

and coacts with a weather strip 45 on the sash to be presently described.

46 and 47 designate respectively -upper and lower semi-circular sash frame sections, one car ryingaglass pane and the other a screen. These is sections are separate units instead of one integral unit, as in Figures 1 and 2, and each is provided with a diametrically extending rail' lfi or 49. The

rails abut edgewiseagainst eachother and are detachably secured together.

rail 48, is formed with a lengthwise groove "55 if for receiving a'tongue 5| on the other rail iil,

and these two rails are formed with arecess S Z between them in which is interlocked 'thef base When assembled, I

53 of the weather strip 45. the upper and lower semi-circular sash sections are rigidly secured together byusc'rewsfia-fexf tending transversely through therail 48 'andthe tongue 5| of the rail 49; The marginof the screen 55 is clamped between a binding strip M and the rail 49 and by similar binding strips -to": the circular portion of the lower sash frame til.

The binding strips are, secured 'in-position 'by' screws 62.

63 designates a handle secured to one are of the j rail 49. This handle. is doubleor' U-shaped and' f is located above the sill; When the sash ,is'to' i be turned in the window frame, to" move the upper sash section with the glass pane into open position, lifting force is'applie'd to the'uppermost branch 63 of the U formation, and when the glass section is entirely open," this i particular branch 53 will lie'against the sill; To again close the glass section and move the screen section,

back into the well, the other branch of tlie'li g formation, which is' now uppermost, is utilized, and this'branch will lie against the sill, when the g glass section is entirely closed,' and the screen. section entirely in the well. -The handle 63 held in positionbytwoof the screws 54,-which,

as before described, secure the upper andlower semi-circular sections together and extend transversely' into the rail 48. r g

The upper and lower sash sections are first assembled together, as a' unit, and this unit I serted in the window opening, the sill facing 4,!

is secured in position by means of the screws I42..- The sill facing .holds the circular window frame The window fram'eis in contracted position. then placed in the window opening in the manner described in connection with the' construction shown in Figures 1 and 2. The window frame is secured in position by the screws 43 and'also additional screws 43*. l"
